Creating a dial indicator Many ATMs use the directions published by Jean Texereau (see section 5.1 of the FAQ) to make a micrometer head for their mirror testers. For an online reference to this sort of project, see Berthold Hamburger's Slitless Tester plans at http://www.geocities.com/CapeCanaveral/9601/atm.html.

To make these sort of micrometers, you need to produce an accurate ruled indicator in either a dial or circumference style. Michael Linder has written some nice PostScript programs to do this. This web page will let you customize his PostScript programs using a web page form.

Complete the form below. Once you click on submit, a custom PostScript file will be generated and sent to your browser. Save the text you receive to a file on your hard drive. Name it with a .ps file extension. For my system (running Windows NT), at a DOS prompt I type copy couder.ps lpt1 [Enter] (my printer is connected to the LPT1 port). I assume that this will work for any DOS or Windows type system with a PostScript printer. Consult your system documentation for help with printing the file.
